When I read about Casey's desire to go with an 8-9 man rotation, I assumed he was referring to players who would get substantial minutes. I assumed other players would play as necessary, in small doses; ie: to give rotation players some rest, when rotation players get into foul trouble, against certain specific matchups...

I think players like Gray, Magloire, Alabi and Forbes/Butler will get minimal minutes. I envision whichever C starts (Gray/Magloire) getting very few minutes at the start of each half to set the defensive tone, much the same way Rasho used to, without getting major minutes and being considered part of the core rotation (except for the few games where there is a large opposing C, where they will get more minutes for the specific matchup).

Kleiza (injury), Carter and one of Gray/Magloire/Alabi will likely be stylin' at the end of the bench most nights. When Kleiza comes back, I think he'll join the battle with Forbes & Butler for backup minutes at the SF spot.

I believe Gray / Magloire will Play with AB whenever AB is on the floor as the first unit. Amir and Ed will be on the second unit... All other players will depand on their defense. during the season it will be a 12 / 14 man rotation especially when playing back to back to back

If by 8-9 man rotation Casey is referring to players who will have the bulk of the minutes, I think you can basically make that up of all the young players. Bayless, DD, JJ, Forbes, Bargs, ED, Amir, Gray, Alabi(?) and Jose should get a lot of burn at the point but he doesn't really qualify as "young". The vets will spell them as needed and probably more when we are in a back-to-back-to-back-to-back scenario.

To me, the SF spot is completely open at the moment. Given JJ's inability to play in a system defensively and his out of control play on the offensive end, I am not counting on him playing huge minutes as the season wears on for a coach who, apparently, wants a disciplined and focused approach. If/when Kleiza is healthy he will be in the mix and I would think Forbes will get a chance, along with Butler.

Given the condensed schedule, I wouldn't be surprised to see the rotation go 11 deep on some nights, so there will be opportunities for everyone.
